PID Control System
PID control is the most common control algorithm in industrial control applications. This article is merely written to share some of the techniques that I developed in Labview Programming to achieve literally zero overshoot. In my case, I wanted to control hydraulics supply and return pressure via control valves. Such control valves take 4-20mA signal to control...
Safety On Board
Need for integrated safety on board controllers
Today, production managers require more productivity through machines. Manufacturing industry suffers from stopping production line to perform day-to-day maintenance activities. Once multi axis motion controller based manufacturing line running hundred's of delta robots is stopped, engineers are required to re-synchronize axis if integrated safety is not implemented in the production line...
Programming FPGA and CRIO
In this article, I wanted to briefly go through few practices that I use to develop a compact rio application. A full Compact RIO controller combines FPGA with real time processor. Labview developer could utilise all target levels to develop machine app that would offer maximum resources utilization and reliability to mention only few of the...
Synchronised multi-axis motion control
Filling Machines and Production Line
Advanced production line in most industries involve many different processes. For instance, yogurt filling machines involves feeding pot material from a coil into a press machine mounted with die. Finished part out of the press and die is empty pots ready for the next stage. Next stage might involve wrapping pots with...
Servo Motion Control
In servo motion, a feedback sensor - usually encoder - is used to continuously measure position and speed of motor to correct motor speed. By using feedback sensor, we can get very accurate results. Most servo motors now have on-board 'Motor Encoder'. However, additional encoders could be placed on the actual mechanical axis to compare against actual line...
Today, vision monitoring is playing a vital role in stopping the spread of Covid-19 disease. Both inside and outside offices, vision inspection is ensuring people are keeping social distances. For decades, visual inspection has been an important aspect for industrial processes. Whether it is used for assisting in sorting bulk materials in pharmaceutical processing, inspecting the quality...
TCP/IP and UDP communication
Benefits of TCP/IP and UDP
Connectivity between devices is become very common and often beneficial essentially in industrial devices communication. Although Modbus, RS485 serial communications have its place still in industrial control and measurement applications, TCP/IP and UDP offers so much diversity that even apps written for I-phone and android could be used to connect with complete...
When 4G technology was adopted in 2008, smartphone apps, streaming services and high speed internet access on-the-go became the norm. Regardless, there was little wireless advancement within production line factories and this is where a lot of 'Big Data' is produced. Sensor data and controls engineering is such a critical operation that it is never deemed safe...
Verification and validation testing of aerospace components, notably pumps, valves, engines, is essential to ensure safe flight. Adequate testing requires exact replication of actual geometrical representation of component position within an aircraft. Further, it is quintessential to simulate environmental conditions surrounding aircraft during the flight. If the component is not subjected under real application conditions during testing...
